Nucleic acid separating vessel, a method of manufacturing the nucleic acid separating vessel, and a method for separating the nucleic acid

Abstract

The sample vessel 1 comprises plurality of vessels 1 a. The vessel 1 a comprises an opening for sample inlet 3, a liquid sample outlet 4, and a silicon oxide composite particles structural body 2 is arranged at the bottom of the vessel 1 a, i.e. the liquid sample outlet 4. The silicon oxide composite particles structural body 2 is a structural body composed of a composite made of plural silicon oxide particles having smaller diameter combined with a resin particle having larger diameter. Accordingly, even if the diameter of the silicon oxide particles 7 is set small in order to maintain the nucleic acid combination ability high, the presence of the resin particles 6 having a large diameter makes it possible to ensure the liquid conduction path, and the nucleic acid separating vessel, which is capable of suppressing decrease of the B/F separating velocity with maintaining the nucleic acid combining ability high can be realized.

What is claimed is:  
     
       1. A nucleic acid separating apparatus comprising a supporting plate that has a plurality of vessels each forming a cavity, said cavity having a shaped composite body therein, said body comprising composite structures of silicon oxide particles supported on a resin particle having a particle size larger than that of said silicon oxide particles, wherein the composite structures are combined three-dimensionally with each other, and wherein each of said vessels has a liquid inlet atop and a liquid outlet at the bottom thereof. 
     
     
       2. The apparatus according to claim  1 , wherein said vessels constitute an array. 
     
     
       3. The apparatus according to claim  1 , wherein said vessels are arranged in an operational relation with a pipetting device.
